Q

What do you need to make a circuit?

A

A battery, wires, and a load

17
Q

What does a battery do?

A

Provide the energy source that pushes electric charges around a
circuit. They have a positive and negative side

18
Q

What are wires?

A

Conductive material that allow electrons to travel

19
Q

What is a load?

A

A device in which, when electrons pass through it, transfer that
energy from electrical to light and heat

20
Q

What is a switch?

A

A device used to open and close a circuit

21
Q

What are the Ohm’s Law equations?

A

V = I x R
I = V/R
R = V/I

22
Q

What is current?

A

The speed of the flow of electrons

23
Q

What is resistance?

A

How difficult it is for electrons to move through the circuit

24
Q

What is voltage?

A

The amount of energy provided to the circuit by the power source

25
Q

Why does the copper wire have to be coiled on an electromagnet?

A

The coiled wire allows for electrons to rapidly flow through it and spin in the same direction which magnetizes the metal core
